I feel similarly. My favorite things about running a business are:

* The variety of problems I get to work on. I write code, I do sales calls, I manage people, I negotiate contracts, I do taxes, you get the idea. I really like learning things and I never get bored.

* I like the intensity. I have to do everything as well as I possibly can, and so I feel like I'm running at close to 100% efficiency at all times. It is very satisfying to feel that you're putting your best work you could.

Both of these things are rare at "normal" jobs. I was lucky enough to have similar experiences when I "worked for the man", but those experiences were never close in terms of quality or intensity.
